Question

I have URI route like:

/dir/:dir1/:val1-:val2

I need a regular expression to:

1. Know if the route match the real URI (es. /category/cars/ferrari-10)

2. Get parameters and values like the follow:

   dir1 => cars

   val1 => ferrari

   val2 => 10

How to do this job?

THank you!

Answer 1

Using regex named groups and preg-match:

$test = "/category/cars/ferrari-10";
$result = preg_match("/^\/[^\/]+\/(?P<dir1>[^\/]+)\/(?P<val1>[^-]+)-(?P<val2>[^\/]+)$/", $test, $matches);
print_r($matches);

The above will result in the following array:

Array
(
    [0] => /category/cars/ferrari-10
    [dir1] => cars
    [1] => cars
    [val1] => ferrari
    [2] => ferrari
    [val2] => 10
    [3] => 10
)

Also, if you want to remove the unnamed groups, you can use the following:

for ($i = 0; $i < count($matches); $i++) {
  unset($matches[$i]);
}
